A bouncy castle is an inflatable structure designed for children to play in. Made from durable materials, it is filled with air to create a soft, springy surface. Bouncy castles come in various shapes and sizes, often featuring colorful designs and themes, making them popular for birthday parties and outdoor events. These inflatable play areas provide a safe environment for kids to jump, bounce, and have fun. They are typically rented from companies that specialize in party supplies and can be set up in backyards, parks, or other open spaces. Safety measures, such as proper anchoring and supervision, are essential during use.
